Protein-binding microarrays: probing disease markers at the interface of proteomics and genomics.

DNA-binding proteins mediate a variety of crucial molecular functions, such as transcriptional regulation and chromosome maintenance, replication and repair, which in turn control cell division and differentiation. The roles of these proteins in disease are currently being investigated using microarray-based approaches. However, these assays can be difficult to adapt to routine diagnosis of complex diseases such as cancer. Here, we review promising alternative approaches involving protein-binding microarrays (PBMs) that probe the interaction of proteins from crude cell or tissue extracts with large collections of synthetic or natural DNA sequences. Recent studies have demonstrated the use of these novel PBM approaches to provide rapid and unbiased characterization of DNA-binding proteins as molecular markers of disease, for example cancer progression or infectious diseases.

On the determination of the interface density of states in a-Si:H/a-SiC:H multilayers

This paper deals with the determination of the interface density of states in amorphous silicon-based multilayers. Photothermal deflection spectroscopy is used to characterize two series of aSi:H/aSi1-xCx:H multilayers, and a new approach in the treatment of experimental dada is used in order to obtain accurate results. From this approach, an upper limit of 10^10 cm-2 is determined for the interface density of states.

Discours économique et évolution institutionnelle, les apports de J. R. Commons

John Roger Commons est, de manière quasi systématique, considéré comme l'un des pères fondateurs de l'ancien institutionnalisme américain. On souligne tout aussi couramment l'influence que la philosophie pragmatiste a pu avoir sur ses travaux, du moins en ce qui concerne son ouvrage de 1934. Plus rares sont les commentateurs soulignant le rôle qu'a le langage, a fortiori le langage de l'économiste, dans l'analyse qu'il fait de l'évolution institutionnelle. Notre but sera de souligner ce fait : pour Commons, dire c'est faire, dans la lignée de la linguistique performativiste, dire c'est agir sur l'évolution institutionnelle. Abstract : John Roger Commons is well known as one of the founders of old institutionnalism. It is current to emphazise his philosophical roots : the american pragmatism, at least in his masterpiece of 1934. On the other hand, it is less frequent to point out the important role that the langage, and a fortiori economics' langage, has in his understanding of institutional evolution. Our aim will be to spotlight this point : for Commons, we can do things with words, on the way of performativist linguistic, when we use words, we influence institutional evolution.

DESENVOLVIMENTO, AUTOMAÇÃO E DESEMPENHO DE UM CONSOLIDÔMETRO COM INTERFACE HOMEM-MÁQUINA

O ensaio de consolidação preconiza a utilização de um consolidômetro. Esse equipamento, até então, não era produzido e comercializado no Brasil. Os modelos não automatizados disponíveis para importação, apesar da proposta de baixo custo, ainda são rústicos e necessitam de contínua calibração dos níveis de pressão durante a realização do ensaio. A exclusividade e intervenção de um técnico durante todo o ensaio, associada à precária coleta de dados nesses modelos, ainda são os principais fatores que têm inviabilizado a consolidação desse ensaio na ciência do solo brasileira. Como alternativa a esses problemas, este trabalho teve por objetivos desenvolver e automatizar um consolidômetro a partir de um Controlador Lógico Programável (CLP) com interface homem-máquina (IHM). O equipamento é constituído de um gabinete de metal que aloja conjuntos de dispositivos pneumáticos, eletrônico-digital e atuadores de força e posição. O funcionamento de cada dispositivo de forma isolado ou conjugado é gerenciado por meio de um software em linguagem de programação ladder, que, a partir de um CLP com IHM incorporada, possibilita armazenar instruções e implementar funções. A interface entre o PC e o consolidômetro é feita pelo software CA-Linker, v 1.0, projetado especificamente para o equipamento. O uso do CLP com IHM incorporada permitiu o desenvolvimento e a automação do consolidômetro. O desempenho e a eficiência do conjunto de dispositivos (pneumáticos, eletrônico-digital e atuadores de força e pressão) foram comprovados pelos excelentes resultados dos valores de deformação e pressão obtidos em função do tempo e, principalmente, do comportamento da curva de compressão, gerada pelos ensaios de compressão.

Relation for the nonequilibrium population of the interface states: effects on the bias dependence of the ideality factors

By an analysis of the exchange of carriers through a semiconductor junction, a general relationship for the nonequilibrium population of the interface states in Schottky barrier diodes has been derived. Based on this relationship, an analytical expression for the ideality factor valid in the whole range of applied bias has been given. This quantity exhibits two different behaviours depending on the value of the applied bias with respect to a critical voltage. This voltage, which depends on the properties of the interfacial layer, constitutes a new parameter to complete the characterization of these junctions. A simple interpretation of the different behaviours of the ideality factor has been given in terms of the nonequilibrium charging properties of interface states, which in turn explains why apparently different approaches have given rise to similar results. Finally, the relevance of our results has been considered on the determination of the density of interface states from nonideal current-voltage characteristics and in the evaluation of the effects of the interfacial layer thickness in metal-insulator-semiconductor tunnelling diodes.

Foam pore size is a critical interface parameter of suction-based wound healing devices.

BACKGROUND: Suction-based wound healing devices with open-pore foam interfaces are widely used to treat complex tissue defects. The impact of changes in physicochemical parameters of the wound interfaces has not been investigated. METHODS: Full-thickness wounds in diabetic mice were treated with occlusive dressing or a suction device with a polyurethane foam interface varying in mean pore size diameter. Wound surface deformation on day 2 was measured on fixed tissues. Histologic cross-sections were analyzed for granulation tissue thickness (hematoxylin and eosin), myofibroblast density (α-smooth muscle actin), blood vessel density (platelet endothelial cell adhesion molecule-1), and cell proliferation (Ki67) on day 7. RESULTS: Polyurethane foam-induced wound surface deformation increased with polyurethane foam pore diameter: 15 percent (small pore size), 60 percent (medium pore size), and 150 percent (large pore size). The extent of wound strain correlated with granulation tissue thickness that increased 1.7-fold in small pore size foam-treated wounds, 2.5-fold in medium pore size foam-treated wounds, and 4.9-fold in large pore size foam-treated wounds (p < 0.05) compared with wounds treated with an occlusive dressing. All polyurethane foams increased the number of myofibroblasts over occlusive dressing, with maximal presence in large pore size foam-treated wounds compared with all other groups (p < 0.05). CONCLUSIONS: The pore size of the interface material of suction devices has a significant impact on the wound healing response. Larger pores increased wound surface strain, tissue growth, and transformation of contractile cells. Modification of the pore size is a powerful approach for meeting biological needs of specific wounds.

Neutron structure of type-III antifreeze protein allows the reconstruction of AFP-ice interface.

Antifreeze proteins (AFPs) inhibit ice growth at sub-zero temperatures. The prototypical type-III AFPs have been extensively studied, notably by X-ray crystallography, solid-state and solution NMR, and mutagenesis, leading to the identification of a compound ice-binding surface (IBS) composed of two adjacent ice-binding sections, each which binds to particular lattice planes of ice crystals, poisoning their growth. This surface, including many hydrophobic and some hydrophilic residues, has been extensively used to model the interaction of AFP with ice. Experimentally observed water molecules facing the IBS have been used in an attempt to validate these models. However, these trials have been hindered by the limited capability of X-ray crystallography to reliably identify all water molecules of the hydration layer. Due to the strong diffraction signal from both the oxygen and deuterium atoms, neutron diffraction provides a more effective way to determine the water molecule positions (as D(2) O). Here we report the successful structure determination at 293 K of fully perdeuterated type-III AFP by joint X-ray and neutron diffraction providing a very detailed description of the protein and its solvent structure. X-ray data were collected to a resolution of 1.05 Å, and neutron Laue data to a resolution of 1.85 Å with a "radically small" crystal volume of 0.13 mm(3). The identification of a tetrahedral water cluster in nuclear scattering density maps has allowed the reconstruction of the IBS-bound ice crystal primary prismatic face. Analysis of the interactions between the IBS and the bound ice crystal primary prismatic face indicates the role of the hydrophobic residues, which are found to bind inside the holes of the ice surface, thus explaining the specificity of AFPs for ice versus water.
